Oh, I didn't know Poland did that too. I made the Soviet Union joke because they seemed to do it with everything, including stuff where the Soviet "invention" came after someone else's, e.g. the Su-24 copy of the F-111 and bits of the Mirage G8 where they proudly announced that the Americans had "confirmed the correctness of the chosen decisions when creating the Su-24". Or, in the case of the Yablochkov Candle, before the Soviet Union even existed.
